Cluster Concepts
Clusters, jobs, and queues
Cluster A group of computers (hosts) running LSF that work together as a single unit,
combining computing power and sharing workload and resources. A cluster
provides a single-system image for disparate computing resources.
Hosts can be grouped into clusters in a number of ways. A cluster could contain:
◆ All the hosts in a single administrative group
◆ All the hosts on one file server or sub-network
◆ Hosts that perform similar functions
Commands:
◆ lshosts—View static resource information about hosts in the cluster
◆ bhosts—View resource and job information about server hosts in the cluster
◆ lsid—View the cluster name
◆ lsclusters—View cluster status and size
Configuration:
◆ Define hosts in your cluster in lsf.cluster.cluster_name
TIP: The name of your cluster should be unique. It should not be the same as any host or queue.
